So I have this on the breadboard right now and it's not quite 100% operational. There is a TON of line noise and the effect of the lfo is very subtle.

For the simplicity's sake I left off TR3, R25 and S3.

I substituted 1n60s, a 2n3906 and a mpf102 instead of the specified semis. Would any of these cause problems?
Also, I don't have a 2pole 4way switch so I just wired the square wave up for testing the circuit.

I adjusted all of the pots to see what difference it would make. The bias definitely changed the sound as did the level pot. When the level is turned down, the noise basically takes over the sound. Could this be coming from the power supply? I've used it to power a couple of other simple audio circuits without this problem.

I just built this circuit myself. What I was wondering is if anyone could tell me how to increase the range of the LFO making able to go slower? Would increasing the value the value of C1 do it. I'm afraid I'm still pretty stupid when it comes to theory of how a lot of electronics work. It's coming slowly, and I'm afraid of frying the circuit because I etched a PCB and it is completely assembled.
